As a rule, the cactus has no leaves. In the process of evolution, they have successfully evolved into bristles, needles, and hairs. The fulfillment of the functions of the leaves had to be taken over by thickened, waxy bloom stems: spherical, elongated, ribbed, depending on the species. Even the most indifferent to plants, buying a blooming cactus changes dramatically. Small, large, a whole group of buds or a single flower conquer with a variety of shades, and some also with aromas. Some plants bloom annually, others every few years. Flowering lasts both several months and less than an hour. Seeds emerge from the fruits, suitable for growing young plants.
